Water shortage concern over Wingfield dump fire

The need for a permanent water supply to a waste centre at Wingfield in northern Adelaide is under consideration after at least three big fires there in the past 18 months.

Fires crews have been tackling the latest blaze since early on Wednesday.

The dump and recycling centre has no mains supply and relies on tanker water.

South Australian Emergency Services Minister Michael O'Brien said repeated fires were a test of Metropolitan and Country Fire Service resources and also tested his patience.

"We're going to attempt in the first instance to see whether we can have permanent water down there and, if that's not the case, actually have a discussion with the operators to determine whether they can put in place facilities that better manage the site," he said.
